Professional Applications & Engineering Value

This 316 stainless steel set screw delivers exceptional engineering value in demanding industrial applications where corrosion resistance and reliable fastening are critical. The 6-32 UNC coarse thread with Class 3A thread fit ensures precise mating with components while resisting loosening from vibration and thermal cycling. The extended tip design provides deeper penetration into shaft surfaces, creating superior holding power for pulleys, gears, and collars in machinery and equipment. Manufactured to ASME B18.3 standards, this headless set screw offers consistent dimensional accuracy for repeatable assembly performance. Ideal for marine, chemical processing, and food equipment applications where RoHS and REACH compliance meets environmental regulations without compromising mechanical performance.

Specification Summary & Compliance

This precision fastener features 6-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy and engagement. The extended tip configuration maintains tight tolerances with tip diameter of 0.092" (-0.005" to 0 tolerance) and tip length of 0.038" (-0.005" to 0 tolerance). Manufacturing compliance includes ASME B18.3 specifications for dimensional standards, along with RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance for environmental safety and restricted substance management.
